I finally connect arduino+lorahat device as end node to loraserver using LMIC Libarary,
now i got the problem, when i try restart/reset the arduino, i cant connect again to loraserver
i got error message like this :
Nov 14 05:28:29 server loraserver: time=“2017-11-14T05:28:29-05:00” level=error msg=“processing rx packet error: get node-session error: node-session does not exist or invalid fcnt or mic” data_base64=QBER3QCALAAB1OtpIs8eqDXYSh7kiDdp
i read some source, that i have to delete the node from appserver and add it again, after that the device connect again, but when i try to restart the device, the problem came back with the same error,
can anyone help me to solve this?
there is a timestamp when i restart device and add it again later,
